Syntax:

file-string-length stream object length

Arguments and Values:

stream - an output character file stream.

object - a string or a character.

length - a non-negative integer, or nil.

Description:

file-string-length returns the difference between what (file-position stream) would be after writing object and its current value, or nil if this cannot be determined.

The returned value corresponds to the current state of _stream_at the time of the call and might not be the same if it is called again when the state of the stream has changed.
